Long-term oxygen therapy (LTOT) has become standard care for the treatment of patients
with chronic obstructive pulmonary disease (COPD) and other severe hypoxemic lung …

The purpose of this study was to compare the efficacy of nasal oxygen delivery by an
inspiratory demand valve, which delivers oxygen only during the inspiratory phase, to …

Purpose Long-term oxygen therapy involves utilizing stationary oxygen concentrators to
allow patients with respiratory illnesses to attain sufficient blood oxygenation via …

Oxygen is necessary for aerobic metabolism. Since the human body cannot produce or store
oxygen, a continuous and adequate delivery of oxygen needs to be secured by oxygen …

BACKGROUND: One century after the introduction of the oxygen flow meter into clinical
practice, we have developed a device, FreeO2, that automatically titrates the oxygen flow …

Background and Objectives. Despite its' proven benefits, oxygen therapy may be
complicated with potential adverse events such as hypoxemia or hyperoxia-driven …

Rationale: Landmark studies of long-term oxygen therapy (LTOT) in patients with chronic
obstructive pulmonary disease (COPD) used arterial oxygen pressure (PaO2) to define …

Purpose It is a challenge to control oxygen saturation (SpO2) in patients with exacerbations
of COPD during admission. We tested a newly developed closed-loop system, O2matic® …

Dear Editor, For chronic obstructive pulmonary disease (COPD) patients at risk of
hypercapnic respiratory failure, excessive oxygen use may lead to loss of hypoxic …
